Apologies in advance for the left-field question ... am in temporary need of a 3.5mm bolt (0.5mm pitch) in order to work on cam chain tensioner on an '84 Honda ATC (Big Red). This was a common size on older metric indicators for example, but I no longer have any. I removed one from the rear K75 indicator but unfortunately it is the coarse thread plastic screw type, and sold my Moto Guzzi (and all spare parts) last year. Smallest metric I can find locally is 4mm.
So for a bonus point - does anyone know of a reasonably accessible bolt of said descript that might be temporarily pilfered ... approx. 1" or longer ..?
Wishing all a better new year!
